Abstract

PURPOSE:To enable the reserved picture recording of a long time program using other recording and reproducing device by outputting an output reception signal of a tuner from is output terminal to the exterior when a recording tape is ended during the picture recording reservation time. CONSTITUTION:When it is the reserved time for picture recording, a power is turned on, and the reception signal of a receiver tuner 2 as selected by an input changeover circuit 3 is inputted via an input signal circuit 4 to a recording and reproducing system 5 to be picture-recorded. When the recording tape is ended in the reproducing system 5, the power is turned off, but because it is still in the reservation time, the power is supplied by the circuit 3 to the tuner 2. Then, an output signal changeover circuit 9 is changed over to the side of a contact piece (b) by a changeover circuit control part 7, and at the same time, a reproducing device connected with a terminal 8 becomes under the picture recording state upon the reserved time. By this method, during the reservation time, even when the recording tape is ended, the reception signal is kept outputting, while the other recording and reproducing device can be in change of picture recording of the remaining part.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a magnetic recording/reproducing device having a recording reservation function.

[Conventional technology]

Home VTRs are equipped with a recording reservation function so that they can record alternate programs or record desired programs when the user is away. According to this, for the desired program to be reserved for recording, if you reserve the channel number + broadcast date and broadcast time on which the program will be broadcast, and turn off the power, the power will automatically turn off when the reserved time arrives. When turned on, the tuner selects the reserved channel and starts recording the reserved program.

For such a VTR with a recording reservation function, for example, the power is turned off at the end of the recording reservation time, as described on page 27 of the instruction manual for "Panasonic video cassette recorder with built-in BS tuner NV-BS3J". However, in addition to this, even during the scheduled recording time, the power is turned off even if the recording tape ends and recording is no longer possible, to prevent unnecessary power consumption. There is.

Therefore, when making a recording reservation for a long program that cannot be recorded on a single recording tape, when the recording of the entire recording tape is finished and the end of the tape is reached during the recording reservation time for this program, the automatic The power is turned off and the rest of the program is not recorded (the longest recording tape currently on the market is SP mode (standard mode)
It is 60 minutes long, and when used in BP mode (3x mode), it is possible to record continuously for 8 hours, so 16
If you want to record a program that is longer than 0 minutes, you can use this 160-minute recording tape and record in EP mode, but if you want to record a program with good image quality without losing image quality, you should use SP mode. It is preferable to record with However, when recording is reserved in the SP mode, as described above, some long programs are left unrecorded.

In order to prevent this, two VTRs may be used and the recording reservation time of a long program may be shared between them. According to this, when one VTR finishes scheduled recording of this program, the other VTR then schedules recording of the remaining part of the program, and thus the entire long program is recorded over two recording tapes. That will happen.

On the other hand, recently, the VTR described in the instruction manual mentioned above
Like the V, it has a built-in satellite broadcast reception tuner (BS tuner) and can also record satellite broadcast programs.
TR also became commercially available. To explain this with reference to FIG. 2, this is provided with a terrestrial broadcast reception tuner 1 for receiving normal television broadcast programs (terrestrial broadcast programs) and a satellite broadcast reception tuner 2, which are switched and controlled by a switching circuit control section 7. The input signal switching circuit 3 allows the user to select one of the tuners. The received signal from the tuner selected by the input signal switching circuit 3 undergoes processing such as AGC (automatic gain control) in the input signal circuit 4, and then is supplied to the recording/reproducing system 5 and recorded on a recording tape. . At the same time, the received signal processed by the input signal circuit 4 passes through the output signal circuit 6 and is supplied from the output terminal 8 to a monitor receiver or the like. Also, during playback, the playback signal from the recording/playback system 5 is transmitted to the output signal circuit 6.
and is output from the output terminal 8.

Such VTRs are also equipped with a recording reservation function. For this reason, scheduled recording is possible for both terrestrial broadcast programs and satellite broadcast programs.

[Problem that the invention seeks to solve]

By the way, even in satellite broadcasting, there are long programs that cannot be recorded on a single recording tape, and there are cases where it is desired to schedule recording of such programs in SP mode without degrading the image quality. In such cases, use a VTR with a built-in satellite reception tuner.
If two units are used, this long-time program can be scheduled to be recorded over two recording tapes in the manner described above.

On the other hand, in recent years, users have started owning two VTRs, and along with this, they have also started owning VTRs with built-in satellite broadcast reception tuners.
V with only the previously owned terrestrial broadcast reception tuner
In most cases, users purchase a VTR with a built-in satellite broadcast reception tuner in addition to a TR, and it is rare for a user to own two VTRs with a built-in satellite broadcast reception tuner. Therefore, conventionally, it has been impossible to reserve and record a long satellite broadcast program that cannot be recorded on one recording tape.

SUMMARY OF THE INVENTION An object of the present invention is to solve this problem and provide a magnetic recording/reproducing device that enables reservation recording of an entire desired program. There is a particular thing.

[Means to solve the problem]

In order to achieve the above object, the present invention provides means for outputting the output reception signal of the tuner to the outside even if the recording tape ends during the reserved recording time.

[Effect]

When the recording tape ends during the scheduled recording time, the input signal circuit,
Power is turned off in the recording/reproducing system and output signal circuit. However, at the same time, the output reception signal of the tuner is outputted from the output terminal to the outside. Therefore, by connecting another magnetic recording/reproducing device to this output terminal and making a recording reservation for the remaining time of the same program, this program can be continuously recorded.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of a magnetic recording/reproducing apparatus according to the present invention, in which 9 is an output signal switching circuit;
Parts corresponding to the figures are given the same reference numerals.

In the figure, an output signal switching circuit 9 is provided between the output circuit 6 and the output terminal 8, and the output signal of the output circuit 6 is connected to the contact a side, and the satellite broadcast reception signal is received to the contact side. Received signals from the tuner 2 are supplied respectively. The output signal switching circuit 9 is switched and controlled by the switching circuit control section 7, and is normally closed to the a side. In addition, satellite broadcast reception tuner 2
Even if the recording tape has finished recording, power is supplied during the reserved recording time, and the power is turned off at the end of the reserved recording time. Other points are the same as the conventional magnetic recording/reproducing apparatus shown in FIG.

Therefore, during normal recording and playback, the output signal switching circuit 9 is closed to the contact a side by the switching circuit control section 7, and the output signal of the output signal circuit 6 passes through the output signal switching circuit 9.
A monitor receiver (not shown) connected to output terminal 8
etc.

Also in the case of recording reservation, the output signal switching circuit 9 is closed to the contact a side. At this time, if the scheduled program to be recorded has a broadcast time that can be recorded on one recording tape, this program can be recorded on this recording tape by scheduled recording similar to the conventional magnetic recording and reproducing device, and there is no particular problem. do not have.

In the case of a recording reservation for a long satellite broadcast program that cannot be recorded on one recording tape, this recording tape is attached to the recording/reproducing system 5 and the satellite broadcast reception tuner 2 is selected by the switching circuit control section 7. , make a recording reservation for the entire broadcast time of this program. At the same time, another magnetic recording and reproducing device that cannot receive satellite broadcasting is connected to the output terminal 8, and in this magnetic recording and reproducing device, the broadcast time of the same program is recorded on the recording tape attached to the recording and reproducing system 5. Make a recording reservation for.

When the set recording reservation time arrives, the power is turned on, and the received signal of the satellite broadcast receiving tuner 2 selected by the input signal switching circuit 3 is supplied to the recording/reproducing system 5 via the input signal circuit 4, and the recording tape is will be recorded. At this time,
This received signal is transferred from the output signal circuit 6 to the output signal switching circuit 9.
．． The signal is supplied to another magnetic recording/reproducing device via the output terminal 8, but since the reserved recording time has not yet come for this magnetic recording/reproducing device, the power is turned off and no recording is performed.

After that, the recording tape in the recording/playback system 5 finishes recording and the tape is released! At the 8th end, the input signal circuit 4. Although the power to the recording/reproducing system 5 and the output signal circuit 6 is turned off, since the recording reservation time is still in progress, the satellite number transmitting/receiving 8 tuner 2 selected by the input signal switching circuit 3 is supplied with power and is not receiving data. in a state. Further, when the input signal circuit 4 and the like are powered off, the switching circuit control section 7 switches the output signal switching circuit 9 to the contact side. Moreover, at the same time, the magnetic recording/reproducing device connected to the output terminal 8 is turned on at the reserved recording time and enters the recording state. Therefore, the received signal from the satellite broadcast reception tuner 2 is directly outputted from the output terminal 8 via the output signal switching circuit 9, and is recorded by another magnetic recording/reproducing device connected thereto.

When the recording reservation time ends, the power is turned off in both magnetic recording and reproducing devices, and the output signal switching circuit 9 is switched to the contact a side again by the switching circuit control section 7.

As described above, in this embodiment, even if the recording tape finishes recording during the recording reservation time, the reception signal of the reserved program continues to be output from the output terminal 8 until the recording reservation time ends, and thereby other To enable recording of the remaining portion of a reserved recording time using a magnetic recording/reproducing device. Therefore, even long satellite broadcast programs that cannot be recorded on one recording tape can be recorded in their entirety.

Note that the above embodiment concerns a magnetic recording and reproducing device that is equipped with a satellite broadcast reception tuner in addition to the conventional terrestrial broadcast reception tuner, but the present invention
It goes without saying that the present invention is not limited to this, and can be applied to magnetic recording and reproducing apparatuses that are capable of making recording reservations for broadcasts that could not be received in the past, such as teletext reception.

〔Effect of the invention〕

As explained above, according to the present invention, any long program that cannot be recorded on one recording tape can be scheduled for recording without exception using the conventional recording reservation function. You can get the same effect.
